I will try to find out the problem
I think the problem is logging in
Whether on WordPress or on the forum

Tested again, the links don't broke after a new topic. And I would say they should not break after creating wpForo topics or posts, as wpForo does not affect on Posts and Pages.

You should find the real problem maker.

After logging in to the WordPress website, the problem occurred again
You can try clearing the cup or opening the page from another browser, you will find that it will not work

Created a new topic, but the Blog posts are working with no problems. The Permalink settings are set right(Post name)

Also, the problem occurs after every login to the site
Attached is a picture that you got now after you logged in to the site

To temporarily solve the problem, you should WordPress settings, then to Permalink Settings, then click on Save

All website links outside the forum
Articles and pages

Please provide Link URL which stops working after forum post.
